Probable cause

The pilot’s inadequate preflight and in-flight fuel management, which resulted in an intermittent loss of engine power due to fuel starvation.

Findings · 4

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during the preflight inspection, in preparation for the local flight to accomplish three touch-and-go landings, he removed the fuel filler caps and visually confirmed what appeared to be an adequate amount of fuel in each tank. The pilot did not use the fuel dip stick to confirm the quantity. The pilot reported that the fuel selector was selected to the right-side fuel tank before departure. After the second takeoff, about 600 ft above ground level (agl) and just before turning crosswind, the engine surged once or twice and then experienced a total loss of engine power. The pilot checked the engine controls and turned left back toward the runway. About 300 ft agl, he switched the fuel selector to the left fuel tank. Seconds later, the engine regained power; however, the airplane had descended low enough that the airplane collided with the tops of mesquite brush and then the ground. Postaccident examination of the airplane revealed that the right fuel tank was empty and that the left fuel tank contained about 10 gallons of fuel. There was no evidence of a breach or fuel leak. The fuselage was substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Seconds later, the engine regained power, however the airplane had descended low enough that the airplane collided with the top(s) of mesquite brush and then the ground. A postaccident examination of the airplane revealed that the right fuel tank was empty, and the left fuel tank contained about 10 gallons of fuel. There was no evidence of a breach or fuel leak. The fuselage was substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
